All will remember that in 1879 Tom

with Prof Kiebs) observations which
tended TO show that in malarious dis
tricts n bacillus inhabits the soil which
can be cultivated so rs to yield a pro-
duct capable, when inoculated. Of pro-
ducing in animals fever Of intermit-
tent type, accompanied by the anatomi-
cal characteristics Of malarious infec-
ton. Subsequently IL was found by
several observers that. during the cold
stage Of ague, spore-containing bacilli,
conjectured to be identical with
those of Crudeli, are to be found in the
blood.
These results have been received by
Psychologists with much misgiving,
partly because the experimental proofs
appeared inadequate. partly because
other observers failed in their en-.
deavors to vcri;y them. DIR. Schiayuzzi

Adriatic, appears to have been more
fortunate. Following the methods .
